Abstract: Flexible pavement construction in India involves different types of layers on the roadbed, such as GSB, WMM, DBM and BC. They are building large amounts of aggregate by breaking rocks. Since the development of highways in India is a continuous process, it has a great impact on natural resources. Due to the depletion of stone, the value of building materials will increase. In some areas where the nature of soil and aggregate are not suitable for highway construction, it is necessary to use different materials for construction, which may reduce the value of pavement construction. The stabilization of the road bed soil will result in a reduction in the thickness of the road surface, and it is economical to do so. Soil stabilization refers to permanently changing any characteristics of the soil to enhance its engineering performance. Starting from the economic purpose of the highway, stable gravel roads can be built in areas with small traffic. In order to stabilize the soil, it can be modified by adding lime, RBI-81, ash and other additives to expand the strength, firmness and performance of the soil, so that it can be used for developing foundations for pavement construction.

Nowadays, a variety of different proprietary additives are also used to stabilize various types of soil, which is usually achieved through physical or chemical stabilization. In the stabilization method, soil stabilization mainly depends on the chemical reaction between the stabilizer and soil minerals to achieve the desired impact.

In this study, RBI 81 stabilizers were used to change the properties of the soil while adding small amounts of Organo-silane (a nanotechnology material) and RBI 81. This added substance disposes of slender ascent and water entrance and lessens water porousness. It responds for all time with soil surface, artificially changes water engrossing silanol gathering to water safe alkyl siloxane at room temperature. It builds soil CBR esteem up to 100%, and diminishes breadth of soil. This added substance keeps up breathability by making a single © 2021, IRJET
